CVE-2018-7208 (opens in a new tab)How to fix?
Upgrade RHEL:7 binutils to version 0:2.27-34.base.el7 or higher.
This issue was patched in RHSA-2018:3032.
NVD Description
Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
In the coff_pointerize_aux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, an index is not validated, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted file, as demonstrated by objcopy of a COFF object.
